This patch does a simple fix to the quota DB driver in order
to ensure its compatibility with python3 and adds the quota
enforcement unit tests to the list of those executed as a part
of the py34 test environment.
Add the concept of resource reservation in neutron.
Usage tracking logic is also updated to support reservations.
Reservations are not however available with the now deprecated
configuration-based quota driver.
The base API controller will now use reservations to perform
quota checks rather than counting resource usage and then
invoking the limit_check routine.
The limit_check routine however has not been removed and
depreacated as a part of this patch. In order to ensure all
quota drivers expose a consistent interface, a
make_reservation method has been added to the configuration
based driver as well. This method simply performs "old-style"
limit checks by counting resource usage and then invoking
limit_check.

Don't fatal error during initialization for missing service providers
Sometime during the split, code was added to fixup driver paths,
which imports service providers even for plugins which are not
in use. That, combined with neutron including default service
providers for VPN and LOADBALANCER, resulted in a really messy
mess in terms of removing VPN from the main neutron test suites.
This change stops the imports, so that if one of the services is
missing, neutron server can still start. It likely breaks the driver
path fixup, which can be fixed outside of this gate blockage.
This merge commit introduces QoS feature into Liberty release of
Neutron.
The feature is documented in: doc/source/devref/quality_of_service.rst
included with the merge patch.
It includes:
- QoS API service plugin with QoS policy and QoS bandwidth limit
(egress) rule support;
- core plugin mechanism to determine supported rule types, with its ML2
implementation;
- new agent extension manager;
- QoS agent extension with pluggable backend QoS drivers (Open vSwitch
and SR-IOV support is included).
To extend network and port core resources with qos_policy_id attribute,
a new ML2 extension driver (qos) was introduced that relies on the QoS
core resource extension (the idea is that eventually we'll get a core
resource extension manager that can be directly reused by core plugins).
Agent-server interaction is based on:
- get_device_details() method that is extended with qos_policy_id;
- a new push/pull mechanism that allows agents and servers to
communicate using oslo.versionedobjects based objects sent on the
wire.
The merge includes the following types of test coverage:
- unit tests;
- functional tests for OVS agent, QoS agent extension, and low level
ovs_lib changes;
- API tests to cover port/network qos_policy_id attribute and new QoS
resources.
This merge also disables qos extension API tests until the service is
enabled in master gate.
Local changes apart from conflicts:
- updated down_revision for qos migration to reflect master expand head;
- disabled qos API tests with gate_hook.sh until we have it enabled in
master gate;
- bumped oslo.versionedobjects requirement to reflect what is in
openstack/requirements' global-requirements.txt

Get rid of exception converter in db/api.py
The exception converter was necessary because the exceptions the
oslo db decorator looked for before were statically defined. The
retry decorator now accepts an exception_checker argument that takes
a function to call on exceptions to determine if they should be
caught.
This patch gets rid of the converted and replaces the one use case
with the new exception_checker argument.

Use a conntrack zone per port in OVS
Conntrack zones per network are not adequate because VMs
on the same host communicating with each other cross iptables
twice. If conntrack is sharing the same zone for each cross,
the first one can remove the connection from the table on a RST
and then the second one marks the RST as invalid.
This patch adjusts the logic to use a conntrack zone per port
instead of per network. In order to avoid interrupting upgrades
or restarts, the initial zone map is built from the existing
iptables rules so existing port->zone mappings are maintained.

Replace internal calls of create_{network, subnet, port}

This patch is clean up to prevent future breakage by eliminating
potentially dangerous code.
l3_db and related code use L2 plugin _get_subnet and related method
unnecessarily instead of get_subnet.
It's dangerous because _get_subnet returns ORM db object which allows
the caller to update db rows directly. So the caller of _get_subnet
may update subnet db without notifying L2 plugin unintentionally.
In that case, L2 plugin or ML2 mechanism driver will be confused.

Add configurable options for HA networks
The L3 HA mechanism creates a project network for HA (VRRP) traffic
among routers. The HA project network uses the first (default) network
